vinohradska writes "There is an interesting article on the periodic table over at Slate: 'Oxford ecologist Philip Stewart has designed a new periodic table of the elements, and it's a hit. American schools are placing orders daily for Stewart's table, and the Royal Society of Chemists recently sent a copy to every British secondary school. Stewart's is the only remake to achieve widespread adoption since Dmitri Mendeleev invented the original periodic table in a fit of brilliance in 1869.' "

Since the painfully brief article buries the most relevant piece of this story 5 pages into a linked slideshow: An image [wikimedia.org] of the chart in question.
::curmudgeony voice:: Dunno... certainly looks prettier, but at quick glance I can gather a lot more information from an "old school" chart.

I like the old chart because all of the detail is right there with the element -- I don't have to go and look at the chart along the right side of the page to get all of its details. But
Yes, the whole 'galaxy' thing is most likely to get children interested in science. They'd have probably worked a dinosaur in there, too, if someone hadn't pointed out that it'd then be sexist, and appeal to boys more than girls, but if it gets the kids interested, and maybe they then move to what we think of as the 'normal' periodic table (being that it's much more dense with its information), it doesn't really hurt anyone.
It just makes it so that the kids won't get jokes like the Periodic Table of Condiments [backtable.org] quite as quickly. (of course, the folks who made it didn't understand the Periodic Table of Elements, or they'd have placed similarly behaving items in a column, with the most reactive elements towards the edges, except for the far right column for things that never go bad)

Although, perhaps I could tear this 'new version' to peices even better if there were a version I could actually SEE posted somewhere on the net. There are fuzzy low-res versions all over the place, but not a one that I can really study.
There are DOZENs if not HUNDREDS of different table formats. I doubt that this one is even moderatly new, excepting perhaps the irrelevant backdrop. The layout depends on what is of interest; a astrophysics professor might have one that accentuates the electron energy states, whereas a chemical engineer might have a chart which accentuates the prevailence of an element in nature.
The current form is incredibly logical. Purly logical. Proton count increases from top-left to bottom right. Happens to correspond to about a half dozen different patterns. God, I can't even think of all the variables that our simple, standard table shows. There is SO much information packed into it. Even if you stripped out everything but the symbol the current table would convey a staggering amount of information. This new table? Mmmm.... not so much.
As for your last comment: It *IS* worse. Because eventually it will have to be discarded and students will have to learn to use the 'normal' periodic table. Sure it will be easier than if they had never heard of elements and protons etc before, but they won't be familiar with it. They will be slower with its use, and more easily frustrated. And public schools are famous for leaving out details that a teacher 'doesn't feel is important'. I tutored college chemistry: anything which adds to confusion without benifit is very bad. There is just too much new information to convey in a short time to have to add yet something else.
All of that said, I read the article hoping to find something which IS better and more intuitive. I believe one could be made which would be better suited to 'general use'; e.g. the casual chemist: the engineer type that looks to a table once in a while to calculate combustion energies, or for the student of general inorganic chemistry. Was bummed to see that POS.

The image of the galaxy is what Tufte calls a "duck" - a decorative style element that dominates a chart without conveying useful information. The color coding is also chartjunk; it conveys nothing that isn't already implicit in an element's location in the chart. Most of the ink in this graphic (galaxy, color fills) conveys zero information.
It gets worse. To keep from obscuring the cute galaxy picture, the designer shrank the atomic numbers to an illegible point size, and then threw away useful data (like atomic weight, electronic configuration and common oxidation states, all of which fit into a rather smaller chart than this which is hanging on my wall.)

The reason they are grouped as they are (vertical groupings are really all that matters) is because, in their atomic state, those species have very similar physical properties.
That being said, oxidized Li is *somewhat* similar to He (atomic radius, further reactivity, etc).

Don't you see that all the orbital or shells [that make for a confusing notation that chemists painfully memorize and physicists gleefully re-explain with Schroedinger's wave equations that mean nothing to most of us] are made much more intuitive in this representation? This new chart can still give those with no education in atomic physics the intuitive recognition of "what should come next", "what's missing" and "what will weigh more" as the old chart has. Consider that chem teachers are are told to regard as advanced any student who understands this notation[search for "Level 3, the student is able to..." [state.tn.us]. Or considered how labored even a chem101 [frostburg.edu] treatment of this material is.
One thing I will concede: Pauling's notion of "electronegativity", so useful to chemists, was clearly related to location of an element on the standard periodic table [changing most strongly as you traversed diagonally from lower left to upper right]...its not so clear here.

Perhaps someday when we see something like e-paper become more affordable we'll see dynamic tables that change according to the relationship you currently want to view. E.g. the table reorders itself when you want to view elements in terms of melting points, or perhaps by relationship when as super atoms (as described in the article slide show).

2) On a positive note, I believe that the visual upgrades to the chart (although, will color blind people have any issues getting the full content from the chart now?) will definitely help students remember and learn emelents easier. The visual separation should definitely increase the ability for students to remember how many different colors, how many elemnts per color per spiral, etc. 3) What I think is the most interesting point of all of this is the relation of the elements being able to be tied back together and done so in a shape that mirrors the overall shape of the galaxy. It's sort of like the movie "Pi" where we can see trends, shapes, circles and spirals all within our life and this would be just one more example.

Overview, not data... (Score:5, Insightful)
The table is not a lookup table for atom details of data. There are so many details (protons, weight, melting point, etc...) in regard to each atom, that no table can really display them proberly.
If you are a chemist you will know most of this by heart, so the table is best for teaching the concepts. To provide an overview.
In my opinion the new table do solve some of the issues the old table had. Especially now that it is round, that allows the end collums to meet.
You could almost say; look at the table and tell me how the atom "behvior groups" are like. Now look at the new table, and answer the same question.
In both cases you still need to learn about the "behvior groups"...
The slideshow is a little misleading (Score:5, Insightful)
Hydrogen is difficult to place in a group because it's basically a single proton with a single electron whizzing around it. In fact, in organic chemistry we usually just refer to hydrogen ions as "protons" -- which they are. The element itself has some properties of halogens and some properties of alkali metals, which is why it sometimes gets put in "both" groups.
Practising chemists usually know where the elements they work with lie in the periodic table. Outside of school use, the main use for periodic tables is to quickly find atomic weights (sometimes also electronic configurations or physical properties). Annotated variants of the "old version" are great for this. If this data can't be found quickly, the periodic table is useless.
Not the first remake (Score:5, Informative)
The strange thing is that high school chemistry books that I've taught from treat Mendeleev as a sort of Socrates/demigod figure, yet make no mention of Moseley's contributions, which really advanced chemistry. We wouldn't know anything about the inner workings of the atom if we didn't know and understand atomic numbers.
As for this new poster... it would be something I'd put up on the wall of my classroom to attract attention and give students a new way of looking at the elements, but for any serious work, we'd still have to use the standard periodic table. There's nothing wrong with looking at the elements in a new way, but that doesn't mean it will be useful beyond generating interest in science.

There is a lot of whitespace. To be as easy to read as a conventional periodic table, this chart would have to be printed much larger. I'd think that a good graphic designer could take care of much of that problem, however.
I like the spiral nature, although that's a little hard to read as well.
As a scientist and educator, I'd say he's done a good job. As a graphic design, the new table leaves a lot to be desired. I wouldn't fault the author for that, the skills necessary for good science or good teaching don't have much in common with the skills for good design.

My kids are going through grade school, and on conference with the teacher, I found out that they dont teach math by having the kids do arithmetic problems over and over until it's second nature. They just briefly touch on subjects like multiplaction and division, to "give the kids a sense of it", in the teachers own words, then move on. The entire curriculum is designed so the stupidest kid in america can pass, and therefore feel good about himself.
I don't know if I suddenly became an old crank, but what the fuck? This is the education strategy we've chosen as we dive headlong into the age of technology?
I moved my kids to private school. I figure the cash spent now is much less than having to support a public school "graduate" into my 90s.
